General Hazards
The following table describes the general hazards that must be addressed when
planning and installing a 9500 MXC system.
Topic Information
Airflow Requirements Rack installations must be made so the airflow required for safe and correct
operation of 9500 MXC is not compromised. For the 9500 MXC Node,
unobstructed air passage must be maintained to each side of the indoor unit,
which requires a minimum of 50 mm (2 inches) of side spacing to any rack
panels, cable bundles or similar.
Circuit Overloading When connecting the 9500 MXC, determine the effect this will have on the
power supply, circuit protection devices, and supply wiring. Check 9500 MXC
power consumption specifications and the supply capability of the power
supply system. This check of capacity must extend to the dc power supply and
not just to an intermediate connection point.
9500 MXC Indoor Unit Earthing The 9500 MXC indoor unit earth must be connected directly to the dc supply
system earthing conductor, or to a bonding jumper from an earthing terminal
bar, or bus to which the dc supply system earthing is connected.
ESD ESD (electrostatic discharge) can damage electronic components. Even if
components remain functional, ESD can cause latent damage that results in
premature failure. Always wear proper ESD grounding straps when changing
or handling the plug-in cards and avoid hand contact with the PCB back-plane
and top-plane. Connect your ESD grounding strap to the combined ESD and
ground connector on the INU rack ear. Spare plug-in cards or cards to be
returned for service must be enclosed in an anti-static bag. When removing a
card from the anti-static bag for installation in an INU, or placing a card in a
bag, do so at the INU and only when connected to the INU via your ESD
grounding strap.
